DEVICE FOR TREATING RECTAL DISEASES.

SPECIFICATION forming part of Letters Patent N0. 601,345, dated March 29, 1898.v

Application nea July 19, i897.

land, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Cooling or Warming Medical Instruments; and I do declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to cooling or Warming medical instruments adapted to be used for curing piles or the like and for any and all uses where a local internal application of cold or heat by induction is desired.

To these ends the invention consists in the construction substantially as shown and described, and particularly pointed out in the claim. v

Figure l is a side elevation of my improved instrument.' Fig. 2 is a longitudinal section thereof. Fig. 3 is a cross-section on line Fig. 1. Fig. 4 is an end elevation of Fig. l.

The instrument thus shown may be made of any suitable material-such as vulcanized rubber, aluminium, brass, or other metal or material-and of suitable size, relatively about as here shown. Inasmuch as either cooling or Warming the partsis to be effected indirectly-that is, through the cooling or heating of the instrument by passing Water through it, the water not coming directly into contact with the parts treated-it is desirable to have as large an exterior surface exposure as may be.found practicable. Hence the stem A is designed to be larger relatively than the stem of an ordinary syringe and is gradually enlarged from about its neck a to its head b.

As here shown, the instrument is T-shaped, having opposite arms c and d of like structure and interchangeable in use. These arms have each an internal channel communicating with the interior of the stem A, and central through said stem and dividing the said channels centrally in the cross-head of the instrument is adiaphragm g. This produces or provides two equal compartments in the instrument, one of which is the inlet-compartment and the other the outlet-compartment. Either of Serial No. 645,045. (No model.)

these may be one or the other compartment, according as the rubber supply-tube h is attached to one arm or the other arm, the discharge-tube 7c of course taking the other arm.

In the head b of the instrument the diaphragm or division-Wall gis provided with a single comparatively small .hole n, through which the water passes under pressure from the supply side to the discharge side ofy the instrument, and if more than one hole be used the holes should be fine, so that their aggregate area will not exceed a single hole of a size substantially and relatively as shown. The normal pressure in the hose will thus be maintained on the pressure side of the instrument, and the conductivity of the material,

coupled with the spray and iioW through the exhaust side, will serve to keep the instrument at a uniform temperature on both sides.

Another distinguishing feature of the invention is the peculiar construction of the exterior of the neck A, which is flattened at m on opposite sides at right angles to the arms c and d, thereby adapting a larger instrument to be used than would Ibe practicable if it were uniformly rounded.

In this instrument no possible mistake can be made in its use, as either arm may be the inlet or the outlet arm for the time being.

Although rubber, gutta-percha, or like material may be used tomake this instrument, I prefer to use metal because of its greater conductivity. In the manufacture from metal the instrument is preferably cast in two equal longitudinal sections, and the diaphragm is made in a separate piece and laid in, after which the parts are fixed together in any suitable Way. The attening of the sides of the stem is deemed important as better adapting the instrument to the person than Aa round instrument'of otherwise the same cross-section.

What I claim is- The instrument substantially as described, the same consisting of the body A and arms c and d disposed at the same relative angle to said body and having open passages through them communicating With the interior of the body, and the said body gradually enlarged from said arms toward its opposite end and IOO Witness my hand to the foregoing speeification this 1st day of July, 1897.
